Operational Testing Underway for StormBreaker, Formerly Known as SDBII
20 Jul 2018 Amy McCullough

"...“Operational test is planned for 12 months. However, there is an effort to accelerate the program,” she told Air Force Magazine via email. “Some F-35 early integration work has begun.”...

...“Raytheon expects follow-on contracts to support F-35B integration as part of the C2D2 program later this year,” said Stagg. “We are on contract, and in the early stages of F/A-18E/F integration for the USN.”

Raytheon recently touted the weapon at the Farnborough International Air Show in England, saying its goal was to emphasize the weapon’s “game-changing capability.” She said international companies, especially those buying the F-35, continue to express interest in the weapon. StormBreaker was designed to fit in the internal bay of the F-35, she noted.

As for the name change, Stagg said it “better characterizes the weapons ability to identify and destroy targets in adverse weather or atmospheric conditions using a tri-mode seeker. ‘Storm’ can also mean an onslaught of incoming threats,” and the weapon is capable of defending against such threats by breaking “through storms with agile precision to destroy its target.”"

The SDB really changes things in several ways.

Even when configured for VLO penetration, it offers a very mixed internal stores arrangement that will bring flexibility to a single sortie.

______1_____ 2 ______ 3 _______ 4 __ 5 ___ 6 ___ 7 __ 8 ______ 9 ______ 10 _______ 11

F-35A Coalition Sample
Station 4: 4 x SDB
Station 5: AIM-120D
Station 7: AIM-120D
Station 8: 1 x 2000lb ASM (GBU-31 JDAM, GBU-32, JSOW)

F-35B UK Coalition Sample
Station 4: 1 x Paveway IV
Station 5: Meteor
Station 7: Meteor
Station 8: 4 x SDB

That gives 5 Precision-Guided Air-to-Surface Weapons, all of which can have multi-mode terminal guidance capabilities when looking at JSOW and SDB combos, with 2 x AIM-120s or Meteors, and the 25mm rotary cannon, with 18,500lb of fuel.

With that configuration, you could execute a multi-layered, flex-nodal mission profile like this:

Ingress phase - EW VLO attack and penetration of IADS while ISR'ing
First priority kill chain Targeting with JSOW, JDAM, LGB
Second Priority kill chain pivot to SEAD from within using SDBs
Third phase - Pivot to on-call for AWACS, ISR/BDA, Air Dominance
Fourth Phase - VLO EW attack/suppress on the way out of the IADS, with potential for MADL-linked targeting of any remaining Air Defense nodes if you have any SDBs left over

The persistence, weapons mix, sensor fusion, network-linking, and ability to do different roles on a whim is going to be scary, especially since you can coordinate fuel status with each other and work that into coverage where work needs to be done.

I'm seeing all the internal pubs and concepts from the 1980s come to fruition in exquisite detail.

Will really be cool when a single Meteor / AIM-120D can be replaced by 2 SACM.

Yes, many think of weapons loads as always being of equal types. Like two Amraams and two JDAM's. Yet, depending on the mission profile that could vary considerably. This could also vary between aircraft in one squadron during a mission. Not like they all have to fly with the same specific weapons load!

Good thanks but the F-35B with its truncated weapons bays have some problems and 3 or 4 in each ?

Three years ago LtGen. Bogdan said this: viewtopic.php?f=60&t=28254&p=307597&hilit=redesign+Bogdan+weapon#p307597
"...“If the weapons bay has to be redesigned to accommodate [new] weapons, we’ll only be redesigning it one time,” Bogdan told reporters after the Norwegian F-35 rollout ceremony in Texas last month.

“We intend on only redesigning the weapons bay one time, so we’re looking at all the weapons together, to figure out what the weapons bay has to look like to put any or all of the weapons on there so you only have to do it once.”..."

It should carry 4 in each bay (8 total):

http://www.tampabaydefensealliance.com/ ... is-updated

The internal weapons bay of the F-35B Joint Strike Fighter cannot fit the required Small Diameter Bomb II weapons load, and a hydraulic line and structural bracket must be redesigned and modified ahead of the planned Block 4 release in fiscal year 2022, the joint program office confirmed this week.

The Air Force and Raytheon plan to begin scaling up production of the 250-pound class, precision-attack munition, except the current F-35B internal weapons bay cannot fit four of the eight required SDB IIs in its current configuration.

In other words, they fit, but there's a hydraulic line and a bracket that need to be slightly shifted / redesigned for proper safer clearance.

If there are 4 SDB's in the bay, are there room for the AIM-120 as well? Does not look like that from the picture, but I could be wrong.

As the inner bay rotates closed, I believe the AIM-120 mounted on that inner bay door will end up basically just above the head or through the head of the crewman in the above photo (the helmet with "ORD" on its rear face).
Take an F-16, stir in A-7, add dollop of F-117 & gob of F-22, sprinkle with AV-8B, stir well, then bake. Whaddya get? An F-35.
